Houston Mayor Sylvester Turner established the Hurricane Harvey Relief Fund in response to inquiries from those hoping to aid victims of the floods that continue to ravage the nation’s fourth-largest city, and Rockets owner Leslie Alexander responded with a $10 million contribution to the charity effort.

Rockets owner Leslie Alexander has told @SylvesterTurner he will up his donation from the $4 million he announced to $10 million.

The billionaire owns a house in Houston and recently pledged another $4 million to local charities. Alexander recently put the Rockets up for sale and is expected to fetch as much as $2 billion in return.

“Our hearts are heavy seeing the devastation that so many of our friends, family and neighbors are experiencing,” the Rockets said in a statement on Monday. “Leslie Alexander has contributed $4 million to Mayor Sylvester Turner’s Hurricane Harvey Relief Fund in an effort to help Clutch City come back stronger than ever. Please stay safe, Houston.”

Rockets point guard Chris Paul joined Alexander, donating $50,000 to the Houston Flood Relief Fund organized by Texans defensive end J.J. Watt that has raised more than $650,000 in less than 24 hours:

The generosity of @CP3's $50k donation is actually what put us over the $500k mark. Phenomenal stuff from donations both large and small.

Rockets teammate Clint Capela has spent the day sharing locations of people in need of help, alerting first responders and volunteers looking to find fellow citizens trapped by the overwhelming rainfall:

Tweet me and I'll share as many emergency situations as I can. Stay safe Houston.

Meanwhile, Houston native Gerald Green shared a heartfelt (and expletive-filled) Instagram video he took while driving his truck around the city and looking for a boat to assist those stuck in their homes:
